From 50efa51afddb50a6ab47ee15614fcf180130888c Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 27 Jan 2014 11:26:33 -0500 Subject: drm/radeon: clean up active vram sizing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If we are not able to properly initialize one of the gpu engines for buffer paging, we limit vram to the size of the cpu visible aperture. We generally either use the gfx or dma engine to do this. Clean up the size limiting code to only adjust the size based on what ring is selected for buffer paging rather than making assumptions about which engine is selected for paging.
